Can I use my ACER Aspire C20-720 as a monitor for a new laptop using the USB 3.0 port?

KB24 · March 14

As the title suggest… my ACER Aspire C20-720 is knackered so I have bought myself a new laptop. I was hoping to still be able to use the old PC as a monitor for my laptop. I see the HDMI is only an “out” but I wondered about the USB 3.0 port (or any other way anyone can suggest)?

Thanks

With HDMI ports is discussed here and wireless: https://www.guidingtech.com/use-your-laptop-as-second-monitor-in-windows/ If your new laptop has USB-C that supports Display Out it should work with an HDMI-USB-C adapter cable.

Thank you for this response. How do I find out what the USB 3.0 port supports please? Can I see this in PC settings?

If the Aspire C20-720 is still able to turn on, you can use the wireless display function to make it a second monitor for the laptop. There is no way to connect it physically.

Thank you. How does that work?

The short answer is no, without an HDMI-In port on your all in one you can't use it as an external display for a different computer. Using it as a wireless display requires that it be fully up and running as a Windows machine, and since the reason you bought the laptop is because the C20-720 wasn't working, that wouldn't be too helpful. If you need a second monitor for the laptop just pick up an inexpensive monitor with HDMI. A 24" should be not much more than $100 new, and thrift stores often have them much cheaper.
